1.	Vander Waal's constants for three different gases are given: {:("Gas", a, b),(X, 3.0, 0.025),(Y,10.0,0.030),(Z,6.0, 0.035):} Which is correct?
Answer» maximum CRITICAL TEMPERATURE - Y most IDEAL behaviour - X maximum molecular volume - Z minimum molecular volume - X Solution :Most ideal = less a, b = x Min molecular volume = less b = x Max molecular volume = more b = z Max critical temperature = more a/b = y .
